New crustacean microcoprolites from the Lower Cretaceous (middle Berriasian-lower Valanginian) of the Neuquén Basin, Southern Mendoza, Argentina

Three new ichnotaxa of crustacean microcoprolites from the Neuquén Basin, Argentina, are described in this paper: Palaxius rahuensis Kietzmann n. isp. (early Valanginian), Palaxius mendozaensis Kietzmann n. isp. and Palaxius malarguensis Kietzmann n. isp. (middle to late Berriasian). In addition, a...
